Help connecting Pro-ject turntable to NAD preamp ?

Hello,

I had to replace an old turntable and went with Pro-Ject Debut Carbon EVO. After assembling the turntable, I am now facing the question of how to connect it to my pre-amp (a NAD PP3) and how to properly "configure" the pre-amp.

The cable that is provided by Pro-Ject is this one: https://www.project-audio.com/en/product/connect-it-e/

But I cannot see an obvious way of connecting the earth wire to the pre-amp.

Finally this all go to a NAD 325 BEE. From there it can go to almost any of the available RCA entry except DISC, is that correct?

Thanks for reading

1. You can connect the earth

1. You can connect the earth wire to the PP3 at the post labeled: GND.
2. You can connect the PP3 to any available RCA input on the 325 BEE including DISC. This amp does not have a phono stage.

Clarification

Thanks for the answer. Just to be sure the legs of the earth wire cannot sit astride the screw, so I have to put one leg outside and the other inside, and then screw back ?

As for the configuration of the PP3, I should select MM, is that right ?

1. Yes. Astride or on one

1. Yes. Astride or on one side as long as it makes firm electrical contact with the screw/nut and nothing else.
2. Grounding is often a capricious task. If you get hum, try disconnecting the earth wire or connecting it to a chassis screw. Whatever works but keep the volume low while experimenting.
3. Yes, MM.

Might have issue with pre-amp

I have tried setting up everything accordingly but I get no sound. I am suspecting an issue with the pre-amp but I have no way of confirming that, as I have no other working turntable with me. But the amp seems to be working fine with another source. Is there anything I can try?

Sure.

Sure.
First, make sure you turn volume down almost all the way on your preamp.
Second, using your finger touch (short) the (+) and (-) pins on one channel of the cartridge or the cable going into the preamp. If the system is functional, that should induce significant hum in that channel. If yes, perhaps the cartridge and/or its wiring is faulty. If not, ......
Third, try the same thing with each of the input cables to the preamp and to the amp. Decent hum indicates functionality.

Seems to work

Thanks. Very useful testing method. I didn't know it. It seems like the problem might have been a contact issue between the turntable socket and the cable plug. At least, it seems to be working now. Thank you for your help.
